What Is a Capital Gains Stock Calculator?
A Capital Gains Stock Calculator is a financial tool designed to calculate the profit or loss from stock investments. It takes into account:
- Buy Price per Share – the price you originally paid for each stock.
- Sell Price per Share – the price at which you sold or plan to sell each stock.
- Number of Shares – how many shares you purchased.
- Capital Gains Tax Rate (%) – the tax percentage applicable on your profit.
Using these inputs, the calculator shows:
- Total Gain (profit before tax)
- Tax Owed (based on your entered tax rate)
- Net Profit (profit after tax deduction)
